The Catastrophic Man-made Global Warming hypothesis is falsifiable, and has been falsified:

1. By the ~32-year global cooling period from ~1945 to ~1977, even as fossil fuel combustion and atmospheric CO2 strongly increased;2. By “The Pause”, when temperature did not significantly increase for about two decades, despite increasing atmospheric CO2 concentrations;3. By the absence of runaway global warming over geologic time, despite much higher CO2 concentrations than at present;4. A hypothetical doubling of CO2 from the so-called “pre-industrial” level of approx. 280ppm to 560ppm would cause AT MOST about 1C of global warming (Christy and McNider 2017, Lewis and Curry 2018) , such that any credible humanmade warming predictions would NOT be dangerous, but would be net-beneficial for humanity and the environment.5. The only conclusive evidence is that increasing atmospheric CO2 is hugely beneficial for the environment and humanity, due to greatly increasing plant and crop yields.

In conclusion, there is no credible evidence of dangerous man-made global warming driven by increasing atmospheric CO2, and ample evidence to the contrary.﻿﻿
